Hello, The OS is RHEL6.5. I have to download and install packages manually. This is not something I can get around.
The GnuRadio version is 3.7.9.1. I am trying to upgrade our version of gnuradio. We have a GUI that I have to make extensive modifications to and decided to switch from Wx to Qt since that is the recommended path going forward. pkg-config does not report anything for qwt. Does the line find_package(Qwt) in the gr-qtgui/CMakeLists.txt check the pkg-config list? Currently I have qwt6.1.2 installed. The directory qwt-6.1.2 was installed in /usr/local/lib64/. There is a shared object in there. I made a symlink to one of them from a directory in LD_LIBRARY_PATH. At the moment, I think I will hold off on installing PyQwt since it is unnecessary per Tom, and I do not need it.
